The Airhead Mach 2 Towable Tube is our budget minded double rider cockpit towable tube. Cockpit tubes provide a safe and comfortable seat, which is recommended for timid and young riders, but still supplies an exciting ride. Four deluxe handles with neoprene knuckle guards provide a secure and comfortable grip. The heavy gauge PVC bladder and durable double-stitched nylon cover ensure years of service. MACH 2 is equipped with a patented Speed Safety Valve for easy inflating and deflating.
